Semi-automatic rifles are highly versatile and used for a variety of purposes, including home defense, hunting, competition, and target sports. They are often used by law enforcement and government agencies as well. These rifles come in a wide range of calibers with numerous options and features available.
The semi-automatic rifle typically utilizes a magazine and fires one round with each squeeze of the trigger. Each time the trigger is pulled, a round is fired, and the used casing is extracted. At the same time, a new bullet is automatically moved into the “ready” position. Semi-autos are unlike lever-action or bolt-action rifles, which require the manual moving of a lever or bolt with each shot to ready another bullet. With a semi-auto rifle, one round will continue to be fired with each squeeze of the trigger until the magazine is emptied. Magazines typically offer a capacity of 2 to 30 rounds or more.
Semi-automatic rifles are made with a wood or synthetic stock. Some synthetic stocks may be adjustable for added comfort and ease of use. The receiver will likely be made of steel, aluminum, or alloy, and barrels come in a wide range of lengths. Some rifles may be scope-ready, while others may have integrated sights.
Some of the best-selling semi-automatic rifles come from top brands like Ruger, Springfield Armory, Kel-Tec, Browning, SIG Sauer, and others.
